Jackson and the CMOS

[Jackson]

Hey guys,

Ever since I rebuilt my rig my mobo appears to be eating my CMOS batteries. So far I've gone through like 4 2032 batteries. What happens is a few weeks go by and my BIOS settings reset. I take the battery out and put it back in but it still will not keep the setting saved but when I put in a new battery it saves the settings for another few weeks. I have no way of checking the battery to see if the "dead" ones have a charge but this is a problem I never encountered before.

Could my mobo be shorting out the batteries?

Any suggestions?

i really don't see how it could beeating that many batteries i mean those things last like forever....i know this didnt help any, but i've never heard of anything like that happening

I've only seen mention of a CMOS battery discharging more quickly on laptops, and even then, it was cutting the life in half. In that case, it would be if you kept running your laptop with discharged batteries, even if you had it plugged in. It put more stress on the CMOS battery, supposedly. I can only suggest from this that maybe your power supply isn't functioning properly, and your CMOS battery is a little overworked. It would more likely be a faulty motherboard though.

How the heck would I phrase that to MSI techsupport. Damn, I think I am stuck with it...

just tell them that they have reversed pollarity on the cmos connector which is causing the cmos batteries to die.  They cant argue with you because they can't prove you wrong.  But MSI does have great support and rma process.  I love MSI.

better yet....  tell the rep that you have found a resister on the board that is installed backwards.  This seems to be causing premature failure of the BIOS battery (gotta use those "smart sounding" terms so they'll buy it) and you'd like your board replaced....

In all seriousness, I have a hard time believing that the power supply is the culprit there, but I suppose its not entirely out of the question.  Sounds more like something on the motherboard to me.

If you can't get anywhere with MSI and wind up stuck with the board, please let me know (so I can buy stock in Duracell!!).

Good luck man.
